330 views

The Big Bang theory has evolved significantly since its inception. Initially proposed in the 1920s, it suggested that the universe expanded from a hot, dense state. Advancements in technology and observations, like the discovery of the cosmic microwave background radiation in 1965, have continually refined the theory. Modern adaptations incorporate inflationary models and dark energy, providing a more comprehensive understanding of the universe's origins and its continued expansion.

FAQs & Answers

  1. What is the Big Bang theory? The Big Bang theory posits that the universe originated from a hot, dense state and has been expanding ever since.
  2. How did the discovery of cosmic microwave background radiation affect the Big Bang theory? The discovery of the cosmic microwave background radiation in 1965 provided strong evidence supporting the Big Bang theory and refined our understanding of the universe's early state.
  3. What are inflationary models in cosmology? Inflationary models explain a rapid expansion of the universe shortly after the Big Bang, helping to address certain inconsistencies in the standard Big Bang theory.
  4. What role does dark energy play in the universe's expansion? Dark energy is a mysterious force driving the acceleration of the universe's expansion, influencing our understanding of its future.
